Who’d’a thunk it?

  • Pixel 3a Boot Failure

    Pixel 3a Boot Failure

    Attempting to rub a smudge off the phone’s screen while it was booting causes problems:

    Pixel 3a boot fail

    Rebooting that sucker cleared the problem, so it wasn’t permanently fatal.

    Whew!

  • Soaker Hose Splices: End Of Life

    Soaker Hose Splices: End Of Life

    The soaker hoses from Mary’s garden all came from someone else and have now reached their second end of life:

    Soaker Hose Splices - end of life
    Soaker Hose Splices – end of life

    Those orange lumps kept them alive for a few more seasons:

    Soaker Hose Splices - harvested

    In the unlikely event I ever give another in-person presentation about 3D printing and what it’s good for, I’ll have some interesting show-n-tell samples. Might have to soak the dirt off, though.

  • Vultures Sunning

    Vultures Sunning

    Spotted after pre-season prep at Mary’s Vassar Farms garden:

    It must feel really good up there atop the old barn, even if they’re sunning themselves to kill off parasites.

    Taken with the Pixel 3a zoomed all the way in at 7× from a bit over 200 feet:

    Then cropped and sharpened just a smidge. Not a great picture, but good enough for practical purposes; the Good Camera + Big Glass takes better pix and is too awkward to carry in my pocket.

  • Blog Impulse Response: Water Heater

    Blog Impulse Response: Water Heater

    Somebody posted a Reddit comment linking to my post about a sensibly implemented water heater anode rod, with predictable results:

    Reddit’s New Hotness has a half-life well under a day, although a steady trickle of incoming traffic will continue forever: The Internet Never Forgets.

    Protip: forcing Reddit URLs to old.reddit.com eliminates the user-hostile site layout. Manual tweaking suffices for my very few visits; you can find browser extensions for on-the-fly rewriting.

  • Adhesive vs. Concrete: Tenacity Thereof

    Adhesive vs. Concrete: Tenacity Thereof

    Sometimes, sticky labels hold on forever:

    Faded NO PARKiNG sign
    Faded NO PARKiNG sign

    It’s standing near what was once the Red Oaks Mill dam, which continues to disintegrate:

    Red Oaks Mill Dam - 2021-02-25
    Red Oaks Mill Dam – 2021-02-25

    Sixteen years ago, the dam was in better shape:

    Red Oaks Mill Dam - 27 Feb 2005
    Red Oaks Mill Dam – 27 Feb 2005

    Maybe the sign was shiny-new back then?

  • Rust Never Sleeps

    Rust Never Sleeps

    Spotted at the corner gas station on a recent walk:

    Gas pump barrier - smashed
    Gas pump barrier – smashed

    Judging from the tire tracks and extrapolating from recent weather, a snowplow driver misjudged the truck’s right-side clearance while backing.

    That big steel tube didn’t put up nearly as much resistance as the architect figured after consulting the relevant building codes:

    Gas pump barrier - right base
    Gas pump barrier – right base

    The paint seems to have been the only thing holding the other side together:

    Gas pump barrier - left base
    Gas pump barrier – left base

    Google Streetview suggests the barriers were new-ish in May 2009:

    Gas pump barrier - newish 2009-05
    Gas pump barrier – newish 2009-05

    Steel is a great construction material, but it doesn’t fare well when installed at grade (or above) where it’s exposed to water and salt. On the other paw, they got over a decade out of it, so maybe it’s as good as it needs to be.

  • 123 Block Links: Blackened!

    123 Block Links: Blackened!

    While looking for something else, I came across my bottle of Aluminum Black, so I just had to do this:

    123 Block Links - blackened
    123 Block Links – blackened

    Looks much snappier than the originals:

    123 Block Links - trial assembly
    123 Block Links – trial assembly

    Those are plain old alloy steel cap screws with a black oxide finish.

    The Aluminum Black package directions tell you to apply it with a swab, rinse, and repeat, which seemed like a lot of work for a handful of pins. Instead, I poured a little into a pill bottle, dumped the pins in, and gave it a good shake to coat the pins, whereupon the cap blew off as the contents proceeded to boil merrily. A quick cold-water rinse calmed things down, with no particular harm done, although I had to chase the threads with a tap to get the black powder out. A layer of oil prettied them up nicely.

    Today I Learned: the reaction between selenium dioxide and bare aluminum is strongly exothermic.
